I was mere hundreds of experience away from level 100. I had to make it count and I had the means to do it: N.U.K.U.L.A.R. Target Painter. What could possibly go wrong?I rode out of Telaari Station in Nagrand and found the nearest rare. I got line of sight and painted the area. Not the target itself; the AoE is pretty big.Ten seconds later the area was covered in ash. A windroc was dead. My skin was charred. And that was it. Redclaw the Feral still lived.It turns out that this is not a ground-penetrating weapon. It explodes on impact, blowing up everything outside the cave and leaving him entirely unharmed.I returned to my garrison and resolved to find another rare, outdoors, with no pesky layer of invincible terrain to save it. While I was there I checked on my completed follower missions, and hit 100.
